Definitely not the new IPA, but a trend. Maybe comparable to NEIPA. Of course, I barf in my mouth every time I hear the word "juicy" used to describe a muddy IPA, as if you can't talk about a NEIPA without using that term. I move to ban that word from the beer lexicon.
Far too many places are jumping on the sour bandwagon, though. Chasing trends. Some really nice ones, even kettle sours. Some really bad ones that people still rave about, because it's a trend. Bad beer is bad beer, whether it's a sour beer or poorly done JUICY NEIPA. Just don't go charging mixed-fermentation prices for your poorly done kettle sour, that REALLY gets me going. And don't go calling your brett beer a sour. 3 years ago you could get away with it, but I feel the beer drinking public is starting to get just enough knowledge on mixed fermentation to call bologna on you, eh!
